[en] We applied the ADAM inversion algorithm to the combined optical and VLT/Sphere disk-resolved data and obtained a detailed 3D shape model with local topography of asteroid (7) Interamnia, the sixth largest body in the main belt. Moreover, we also estimated the size and bulk density of Interamnia. The resulting shape model is rather round and lacking any large scale concavities or even topographic features such as impact craters although we should be able to resolve those as large as ̃40 km.
